SPLIT HUB HEAD FOR CYLINDERS FOR SPINNING FRAMES, SPOOLERS, AND CYLINDERS OF LIKE NATURE.

Application filed March 7, 1922.

To all whom it may concern Be it known that we, VVINoo HERnoN and JOSEPH H. Jns'rnn, citizens of the United States, and residents of the city of Augusta,

county of Richmond, and State of Georgia, have invented certain new and Improved Split Hub Heads for Cylinders for'splnning Frames, Spoolers, and Cylinders of like Nature, of which the following 1s a 0 full, clear, and exact description.

Our invention relates to improvements in spinning frame cylinders, and it consists in the combinations, structures and arrange ments herein described and claimed.

An object of our invention is to provlde a spinning frame cylinder which is constructed in such manner as to permit of the disassembly of the cylinder and the re moval or replacement of a shaft upon which the cylinder is mounted with the necessity of removing the cylinder from the cylinder frame obviated.

A further object of our invention is to provide in a cylinder ofthe character de 5 scribed a novel cylinder head.

Other objects and advantages will be apparent from the following description, and the novel features of the invention will be particularly outlined in the appended claims.

Our invention is illustrated in the accompanying drawings, forming a part of this application, in which:

Figure 1 is a fragmentary view mainly in side elevation and partly in section of a cylinder head embodying our invention operatively applied,

igure 2 is an enlarged side elevation of the cylinder heads shown in Figure 1, and

Figure 3 is an end View head.

Referring now to the drawings, the numeral l designates a shaft on a spinning frame, not shown. The shaft 1 carries the spinning cylinder in whichan embodiment of our invention is comprised and is in general of conventional construction, differing therefrom only in the particulars which will be hereinafter specifically set forth.

In carrying out our invention, a head 2 having a hub 3 provided with a. bore of uniform diameter throughout its entire length is slipped over the end of the shaft 1 and is secured in place on the shaft by 5 means of a set screw 1 carried by the hub of the cylinder Serial No. 541,654.

and adapted to engage a longitudinal slot or key-way 5 in the shaft. A stop pin 6 is fixed in the shaft 1 and limits the movement of the head 2 in one direction along the shaft. The head 2 differs from the conventional construction in that the bore thereof is uniform in diameter for its entire length while the bore of an ordinary head is tapered. The head 2 is releasably secured to the shaft in the manner described; whereas the conventional head is secured to the shaft by caulking or in a like manner.

A head 7 which embodies the present invention is slipped over the end of the shaft 1 and is moved along the latter until positioned at a desired distance from the head 2. As illustrated to advantage in the drawings, the head 7 comprises a body 8 having a peripheral flange 9 formed thereon adjacent to its outer end and having an integral hub 10 extending from the inner end thereof. The outer end or face of the head 7 is recessed, as at 11, nearly to the hub 10 and the latter is provided with a bore 12 extending therethrough into communication with the recess 11. The bore 12 is of uniform diameter throughout its length and is of such diameter as to permit slidable movement of the head along the shaft 1 without permitting undue play between these parts. A key-way 13 formed in the wall of the bore 12 is adapted to engage a spline 14 carried by the shaft 1, whereby the head 7 is held against rotation relatively to the shaft 1 while being per mitted to move longitudinally thereof.

The hub 10 is split from its outer end by slits 1515 extending through its walls in a diametrical plane and terminating short of but adjacent to the juncture of the hub 10 with the body 8. It is to be observed at this point that the plane of the slits 1515 extends substantially at right angles to the plane of the key-way 13.

A collar 16 is s'lidably mounted upon the hub 10 and is fashioned with diametrically opposed bosses l7 and 18 respectively. The collar '16 is arranged upon the slitted portion of the hub 10 so that the bosses 17 and 18 lie in a plane extending substantially at right angles to the plane of the slits 15-15. The collar 16 is then secured to one portion of the split hub by means of a pin 19 projected through the boss 18 into engagement with the bore of the split hub.

A. set screw 20 engaging a threaded bore 21 extending radially through the boss 17 is now tightened to occasion a pressure upon the other portion of the split hub, thereby constricting the bore of the hub and lamping the portions of the split hub to the shaft.

A cylinder body 22 is then mounted upon the heads 2 and 7 and is secured thereon in any suitable known manner. The cylinder 22 differs from the conventional cylinder only in that it is provided with openings 23 and 24 through its walls, which openings are located respectively in position to afford access to the set screws 4 and 20 and to permit of tools being inserted through the openings to effect the manipulation of the set screws, as desired.

From the foregoing description of the various parts of the device the operation thereof may be readily understood.

In the event that the shaft 1 should be broken in service and the replacement thereof is necessary, the set screws 4 and 20 are loosened and the broken shaft is withdrawn from the cylinder with the necessity of tearing down the cylinder or removing it from the spinning frame obviated. In the event that the shaft 1 should be broken at a point between the heads 2 and 7, a suitable tool for gripping the shaft 1 may be inserted through the openings 23 and 24: and placed in engagement with the shaft intermediately of the heads 2 and 7, whereupon the broken portions of the shaft may be worked free of the heads. Grooves 25 may be formed in the shaft at intervals between the pin 6 and the proximate end of the hub 10 to insure the engagement of a gripping tool with the shaft, In the event that the shaft has been broken at a point between the heads 2 and 7 the broken end portion of the shaft cannot fall between the heads since it must of necessity be of greater length than the distance between the hubs 3 and 10 as the combined length of the hub 3 and the portion of the shaft projecting beyond the end of the head 2 remote from the hub 10 is greater than the distance between the proximate ends of the hubs 3 and 10.

lVith a cylinder of ordinary construction. the breaking of a shaft and the consequent replacement thereof necessitated the removal of the cylinder from the spinning frame and the removal of the spinning bands and associated parts from the cylinder as well as the disassembly of the cylinder and the removal of the outer head thereof from the cylinder body, This must be done preliminarily to the replacement of the shaft and as a result considerable time was lost and the production of a spinning machine of which the cylinder was a part was curtailed appreciably on account of the necessity of replacement of a shaft. As will be understood from the foregoing description, a cylinder embodying our invention need not be removed from the spinning frame nor torn apart to permit of the replacement of a broken shaft and as a result the repairs necessitated by the breaking of a shaft can be elfected in considerably less time than has been possible heretofore, thereby effecting a saving of labor, time and production. Moreover, since the head embodying our invention is adjustably and detachably secured to the shaft it can be slidably moved back andforth on the shaft and positioned at different distances from the head 2 in order to compensate for deviations of a cylini der body from a specified length. Moreover, since the hub of the head embodying our invention is splitand can be constricted in the manner described, the hub may be longer than is ordinary and thus provide a bearing surface on the shaft which isof sufiicient extent to stabilize the head? to a-degree heretofore impossible of attainment.

Obviously, our invention is susceptible of embodiment in forms other than that which illustrated in the accompanying drawings and we, therefore, consider as our own all modifications and adaptations orforms of the device disclosed herein which fairly fall within the scope of the appended claims.
